From the author of TBH and The Friendship List, Lisa Greenwald, comes a new series about the drama of middle school—and the group chat. Sadie and Olive have never been part of their class’s popular friend group. Those girls—Pella, Annabelle, Cleo, and The Other Sadie—seem like creatures from another planet. They wear the trendiest clothes, have the best hair, flirt with the cutest boys, and speak their own language. By comparison, Sadie and Olive are invisible . . . until Sadie is accidentally added to the popular girls’ group chat. Armed with an inside perspective, Sadie sets out to join the friend group—IRL—before they figure out that they’ve got the wrong Sadie.
